Weird question about asumi-chan

I swear i remember there was a extra of the manga where kurocan says that the name asumi, which is rat in japanese, was given cuz she twiches alot (its so hard writing this seriously kkkkk). Ive looked for that extra and even did a surface level research on kuros's twitter but i cant find anything. I vividly remember the authors weird can head self insert saying that and im kind going crazy cuz i remember so vividly.

Weird question i know but doesnt it makes sense? And there is aways alot of focus on the whole twitching thing
